Friendly Interface
Bright LED’s show the current status even from a distance. A menu-driven display aids the user throughout the operations with running messages and clear prompts. All relevant parameters can be simply adjusted and will remain memorized until overwritten.
Programmable Hold System
The hold function allows the user to stop the regulating action of the controller for programmable time periods. It is possible to activate the hold periods in correspondence to programmed operations, such as plant maintenance and cleaning procedures.
Good Laboratory Practice (GLP)
Last calibration data internally recorded for traceability including calibration date and time, cell constant, calibration solution values.
PC Connectivity (HI710222 only)
RS485 standard is a digital transmission method that allows long lines connections. Its current-loop system makes this standard suitable for data transmission in noisy environments. Data transmission from the instrument to the PC is possible with the HI 92500 Windows® compatible application software offered by Hanna Instruments.
Programmable Cleaning Cycles
Heavy-duty applications often require almost continuous probe maintenance. Elements such as suspended solids, fat, oils, pigments and microorganisms can quickly deposit and soil the electrode. Programmable cleaning cycles allow for scheduled maintenance to keep the probe functioning optimally.
Automatic Temperature Compensation
A 2-wire Pt100 can be connected to ensure fast, accurately compensated readings even during sudden temperature fluctuations.
